It is normal to assume that you and all your biological siblings share the same ancestor but that’s not exactly true since there are chances that children with the same parents might have different ancestry test results.
There are 3 different ways in which you can determine ancestry through DNA testing which are:
- Test for Y-Chromosome – the Y-Chromosome DNA testing is a sex-determining chromosome that is only present in males. The Y-chromosome is passed down from generation to generation in the male line of inheritance. The Y- Y-chromosome is usually used to trace back the paternal ancestry and it can be traced back to 100 and thousands of years however there is a flaw in the system when it comes to determining the paternal ancestry in females since females do not carry this Y-chromosome. Because of this the paternal ancestry of a female is not possible, and can only be guessed if the male relatives of the female get the ancestry test.
- Mitochondrial DNA testing– mitochondrial DNA is found in the mitochondria of a person and is only passed down by a mother to their children without that much change. This DNA test is used to determine the maternal ancestry of a person and can be traced back as far as 200,000 years.
- Autosomal DNA-this represent a person’s genome excluding the sex chromosomes. Autosomal DNA can be used to trace both paternal and maternal ancestors. It can be used to trace back several generations.
If you want to have an Ancestry DNA Testing Denver solely for peace of mind and not for legal reasons, you have the option to collect your DNA at home and send it to the “Ancestry DNA Testing Denver” center for testing. Here, you will also get more options for other DNA tests, including Immigration DNA tests, Paternity, Prenatal, Sibling DNA testing, and many more.
